Android的Handler几种常见的传值方式

public class handlerThread2 extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

//System.out.println("activity线程ID:"+Thread.currentThread().getId());
HandlerThread handlerThread = new HandlerThread("handlerThread");
handlerThread.start();
MyHandler handler = new MyHandler(handlerThread.getLooper());
Message msg = handler.obtainMessage();

//msg.arg1 = 123;//传递整型数据
//msg.obj = "asd";传递object类型

//利用bundle对象来传值
Bundle b = new Bundle();
b.putInt("ID", 12);
b.putString("name", "thinkpad");
msg.setData(b);

msg.sendToTarget();
}
class MyHandler extends Handler {

public MyHandler() {
super();
}

public MyHandler(Looper looper) {
super(looper);
}

@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
//int args = msg.arg1;
//String s = (String)msg.obj;

//获取bundle对象的值
Bundle b = msg.getData();
int id = b.getInt("ID");
String name = b.getString("name");
System.out.println("id is "+id+", name is "+name);

//System.out.println("handler线程ID:"+Thread.currentThread().getId());
}

}
